Mawson Gold Limited announced Southern Cross Gold Ltd. has released three drillholes SDDSC105, 106 and 109 from the Apollo area at its 100%-owned Sunday Creek Project in Victoria, Australia. SDDSC105 was terminated early due to it deviating too far from target. The hole intercepted near-miss alteration including sericite-pyrite +/- carbonate alteration associated with mineralisation at the top of the hole over a 90 m zone from (197 m to 287 m).

Highlights included 1.0 m @ 1.7 g/t AuEq (1.7 g/t Au, 0.0% Sb) from 221.0 m and 0.4 m @ 1.7 g/t AuEq (1.7 g/t Au, 0.0% Sb) from 225.0 m. SDDSC106 was drilled east to west through into the Apollo Deep area and successfully traversed 6 high-grade vein sets over a 200 m interval. SDDSC106 contains eight intervals >15 g/t Au (up to 59.9 g/t Au) and eight intervals of >5 % Sb (up to 34.5% Sb) . This hole confirms the mineral system is increasing in grade at depth as it does across the Sunday Creek field.

This observation is considered extremely promising. Several drillholes to report (SDDSC108A, 112W1 and 116) will continue to test the trend of higher grades and thickness at depth at Apollo. Analytical samples are transported to the Bendigo facility of On Site Laboratory Services ("On Site") which operates under both an ISO 9001 and NATA quality systems. Samples were prepared and analyzed for gold using the fire assay technique (PE01S method; 25 gram charge), followed by measuring the gold in solution with flame AAS equipment.

Samples for multi-element analysis (BM011 and over-range methods as required) use aqua regia digestion and ICP-MS analysis. The QA/QC program of Southern Cross Gold consists of the systematic insertion of certified standards of known gold content, blanks within interpreted mineralized rock and quarter core duplicates. In addition, On Site inserts blanks and standards into the analytical process.

MAW considers that both gold and antimony that are included in the gold equivalent calculation ("AuEq") have reasonable potential to be recovered at Sunday Creek, given current geochemical understanding, historic production statistics and geologically analogous mining operations. Historically, ore from Sunday Creek was treated onsite or shipped to the Costerfield mine, located 54 km to the northwest of the project, for processing during WW1. The Costerfield mine corridor, now owned by Mandalay Resources Ltd. contains two million ounces of equivalent gold (Mandalay Third Quarter 2021 Results), and in 2020 was the sixth highest-grade global underground mine and a top 5 global producer of antimony.
